Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sophisticated and accurate rapid point-of-care tests are implemented, then diagnostic accuracy is improved, but device complexity increases making them inaccessible outside laboratories and hospitals
Solution Approach 1:
The patent combines multiple functions (sensing, data processing, result presentation, and electronic device integration) into a single handheld diagnostic device. The sensor array detects test results while onboard algorithms process the data and generate presentable outputs, eliminating the need for separate complex laboratory equipment and making accurate diagnostics portable and accessible at point-of-care settings.
Solution Approach 2:
The handheld device is designed to perform multiple diagnostic functions using a single integrated platform. It can interface with various electronic devices (smartphones, tablets, computers) and process different types of test data through universal algorithms, allowing one device to replace multiple specialized laboratory instruments while maintaining diagnostic accuracy.
2Extent of automation
If automated data recordal and electronic medical record integration are implemented, then data management capability is improved, but requirement for IT infrastructure increases
Solution Approach 1:
The handheld device acts as an intermediary between the test cartridge and electronic medical records systems. It automatically captures test data through sensors, processes the information locally using onboard algorithms, and then transmits results to electronic devices for EMR integration. This intermediary approach enables automated data recordal without requiring complex centralized IT infrastructure at the point-of-care location.
Solution Approach 2:
The device performs self-service data processing by automatically capturing test results through sensors, analyzing the data using onboard algorithms, and generating presentable outputs without requiring manual data entry or complex external processing systems. This automation reduces the burden on IT infrastructure while maintaining comprehensive data management capabilities.
3Ease of operation
If quantitative and qualitative diagnostic tests are performed without laboratory equipment, then portability is improved, but measurement precision may be compromised
Solution Approach 1:
The patent replaces complex mechanical and optical laboratory measurement systems with electronic sensors and digital signal processing. The sensor array detects test results electronically, and onboard algorithms process the signals to generate accurate quantitative and qualitative results. This substitution of mechanical systems with electronic ones maintains measurement precision while enabling portability and eliminating the need for bulky laboratory equipment.
